. I enonnn-srnrr nairrne BLOC My invention relates'to ground strip nail- 7 forms of ground or nailing blocks and to provide a ground or nailing block having its side faces corrugated, roughened or scored in order that said block may be very firmly anchored and bonded to the wall members or tile between which it is positioned and which bonding effect is produced by means of mortar or cement located in the joints between the roughened side faces of the block and the adjacent faces of the tile or wall forming members. I 1 7 Further objects of' niy invention are,'.to

provide a ground strip nailing block that is relatively simple in construction, inexpensive of manufacture and which wlll form a convenient and. substantial member to which ground strips may be firmly secured and which latter serve as supports and polnts of attachment-for baseboards, casings, moldings and the like,.as well asstops and gauges for the mortar or like finishing materialthat isnpplied to the surface of the tile .ormasonry walls in which the blocks are positioned. I

, WVith the foregoing and other'objects in view, my lnvent on consistsin certaln novel features I of construction and arrangement; of

parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawings inwhich: 1 y

Figs. 5 and 6 are horizontal modified forms of the block.

Fig. 7 is a perspective View of afurther modified form of the block.

In the construction of the preferred em bodiment of my improved nailing block, I make use of a strip or elongated rectangular sections of section 10 of wood and both ends thereof are notched or indented as designated by 11 ing blocks that are used in tile or masonry walls and the principal objects of my 1n- I Application filed July 22, 1926. Serial n. 124,171.

' Applied to both ends of thebody of the the body oftheblock, thereby firmly securing said sections of material to said. block. The width of the reticulated section is such that it fits within the notch 11 at the end of the block and thegreater portionsof the I twosections of reticulated material extend lengthwise over the sidesof the blockand terminate adjacent to eachother at a point near the center of saidblock. Thus, when readily key and bond with the result that the block will be very securely anchored and tied to thewall tilesor blocks, 7

the twosections ofxreticulated material are 7 pressed onto the block, they form roughened side. faces to which mortar or cement will When the nailing blocks are positioned between the wall tile or'blocks, said nailing blocks are. arranged so that theirnarrow ,edges 'lie flush. with the faces of-the wall vtile and; the ground strips G are now se- {cured to the nailing blocks by driving nails through said'strips into said blocks. Where the nailing blocks are arranged between the tile, or wall members in the lower course or that course immediately abovea floor, :the

be provided with irregular or corrugated faces by running said blocks or the long In some instances,: the nailing blocks may a no strips that are divided into the blocks through suitable machinery that cuts or formsgrooves in the side faces of said blocks and'wliich grooves may be V-shape asfillustrated in'Fig. '5, square or channel-shape, as illustrated in Fig. .6. Further, the side faces of the blocks may be roughened or corrugated as illustratedin Fig. 7 by passing said blocks between pressure rollers, the periphcries of which are toothed, ribbed or corrugated. V r

'The nailing blocks, contemplated by my "invention may-be'made in various sizesto correspond with the standard sizes ofwa llforming tile and blocks, and any suitable and convenient means may be employed to provide said blocks with roughened, indented or corrugated side faces that will provide a firm and substantial anchorage'for mortar that is used inbonding said blocks to the wall-forming members.

7 It will he understood that minor changes in the size, form and construction of the various parts of my iinproNed ground strip nailing block may be made and substituted forthose herein shown and described without departing from the spirit of inyinvention, the scope of which is set forth in the appended claims.

I claim asmy invention -1. The combination with a ground strip nailing block having notches in its ends, of sections of reticulated material positioned in the notches in the ends of said block and extending inwardly from said notches toward the center of said block on the side faces thereof.

2.- As a new article of manufacture, a

, block adapted to be positioned between Wall forming .members and to serve as a ground strip nailing'block, the thickness of which block is uniform'throughoutitslength and width so that the body .of the block com pletely fills the wall joint in which said block is positioned, .the side edges of which block are adapted to lie flush with the side faces 4. As a new article of manufacture, a

block adapted to be positioned between Wall forming members and to serve as a ground strip nailing block, the thickness of which block is uniform throughout its length and width so that thdbody of the block com- 'pletely fills the wall joint inwhich said block 7 is positioned, the side edges of which block are adapted to lie flush with the side faces of the wall members between which saidblock is positioned, and sections of irregular material applied to the side faces of said block. 3

5. As a new article of manufacture, a block adapted to be positioned between wall forming members and to serve as aground strip nailing block, the thickness of which block is uniform throughout its length and width so that the body of the block completely fills the wall joint in which said block is positioned, the side edges of which block are adapted to lie flush with the side faces, of the wall members between which said block is positioned, and sections of reticulated material applied to the side faces of said block.

6. As a new article of manufacture, 'a block adapted to be positioned betweenwall forming members and to serve as a ground strip nailing block, the thickness of which block is-uniform throughout the length and widthof the block, whereby said block will completely fili the wa ll joint in which said block is positioned, the side edges of which block are adapted to 'lie' flush with theside faces of the wall members between which said block is positioned, and sections of reticulated material pressed onto 1 the end portions of the side faces of sa-idblock;

In testimony whereofI'afiiX my signature.
